Answer:
x= 5.6
Step-by-step explanation:
Basically, if you do 7÷5 it would equal 1.4 so you would have to multiply 4x1.4 which would equal 5.6.
In conclusion 4/7 = 5.6/5
Answer:
First option: 
Step-by-step explanation:
The missing graph is attached.
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
We can observe that:
1. Both lines have the same y-intercept:

2. The lines are solid, then the symbol of the inequality must be
or
.
3. Since both shaded regions are below the solid lines, the symbol is:

Based on this and looking at the options given, we can conclude that the graph represents the following system of inequalities:

Answer:
50 dimes and 29 nickels
Step-by-step explanation:
Answer: x=sqrt10-2, x=-sqrt10-2
Step-by-step explanation: square root both sides of the equation.
x+2=sqrt10,-sqrt10
subtract 2 from both sides of the equation
x=sqrt10-2, -sqrt10-2
